Odell Beckham, WR, LSU

LSU receiver Odell Beckham caught some flak for hitting just seven reps on the bench press, but he ultimately showed what his true game is about: speed.

Beckham tied for seventh among receivers with a 4.43-second 40-yard dash, matching the time of Clemson star Sammy Watkins, who could be the first receiver taken.

He also showed some solid explosiveness with a 38.5-inch vertical jump.

The biggest bumps for Beckham came in the 20- and 60-yard shuttles, where he turned in times of 3.94 and 10.93 seconds, respectively. Those numbers put him in the top three among all receivers in both drills.

He was one of the biggest winners at the position from across the country and the strong combine showing might have solidified Beckham as a first-round pick.

Johnny Manziel, QB, Texas A&M

Johnny Manziel showed off his unrivaled playmaking ability time and time again while at Texas A&M, but many were intrigued to see how that would translate on paper.

The answer: quite well.

The 2012 Heisman Trophy winner measured just shy of 6'0", but addressed that issue perfectly when speaking with reporters.

"I play with a lot of heart,” Manziel said. “I play with a lot of passion. I feel I play like I’m 10-feet tall. Those measurements to me are just a number.”

Manziel turned over the No. 4 40-yard dash among quarterbacks at 4.68 seconds, but his strong day didn't end there.

He was fifth in the vertical jump (31.5 inches) and fourth in the broad jump (9'5"). Most importantly, he showed where that quickness and improv ability comes from with the second-best three-cone drill (6.75 seconds) and the top 20-yard shuttle at 4.03 seconds.

After Manziel showed the numbers behind the tape, the Houston Texans will just have to decide whether or not he's worth a No. 1 overall pick.

Jake Matthews, OL, Texas A&M

Texas A&M's Jake Matthews didn't have to do a lot to boost his already strong stock at the combine, but he turned in a great day anyway.

At 6'5", 308 pounds, Matthews isn't the biggest physical specimen in the draft, but he's as fundamentally sound as any lineman and showed that he does have some athleticism as well.

He ran a solid 5.07-second 40 and tied for third in the vertical jump at 30.5 inches.

The most impressive part of his performance was the three-cone drill, where he turned in the position's second-best time at 7.34 seconds, showing that he'll be able to hang with the speedy rushers at the next level.

Matthews is a first-round lock and will likely be taken in the top 10—if not top five—of the draft.

Donte Moncrief, WR, Ole Miss

Ole Miss standout Donte Moncrief had one of the best combine performances of any receiver from any conference.

Measuring in at 6'2", 221 pounds, he has the size to be a dominant receiver at the next level and he showed some incredible speed and quickness for his size.

He turned in an official 4.40-second 40-yard dash—the No. 3 time among all receivers. The only two receivers to turn in better times, Oregon State's Brandin Cooks and Pitt State's John Brown, measured in at 5'10" and less than 190 pounds.

Greg Robinson, OL, Auburn

Auburn's Greg Robinson entered the combine hoping to show that he should be the top tackle taken, and he made a great case.

His size is ideal at 6'5", 332 pounds, but he carries that weight extremely well.

He was No. 2 among linemen in the 40-yard dash with a time of 4.92 seconds while also churning out a solid 32 reps on the bench press and finishing third with a 9'5" broad jump.

While those numbers are outstanding, he was most impressive in position drills, as NFL.com's Bucky Brooks explained:

Robinson moved like a dancing bear on the turf, alleviating any concerns about his ability to take on elite pass rushers off the edge. Overall, the stellar workout in front of hundreds of scouts and coaches will not only send Robinson's draft stock soaring -- it could make him enter discussion as the draft's top overall prospect.

You want the toughest quarterback in the SEC, plays through every injury you can possibly think of. He can run the ball, he's a dual (threat) quarterback, but he can also throw the ball. I mean, he's a winner. At the end of the day, isn't that what quarterbacks are about? Isn't that what you want as a quarterback, is a winner? He's not a guy who's gonna be rah-rah, but when he does speak, it's gonna mean a lot.

After a strong showing at the combine, others are going to be asking the same question.
